When more than two different alleles control a trait?
This phenomenon is known as multiple allelism, where there are more than two different variations of a gene (alleles) that can affect a single trait. In this case, individuals can inherit one of several possible alleles for the trait. Examples include the ABO blood group system in humans, where there are three alleles (IA, IB, i) that determine a person's blood type.
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What is a gene that has 3 or more alleles for a single trait?
An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
A single gene has 3 or more alternative forms These are called?
The different forms or variations of a gene are called alleles. Thank you<3
What is an example of a human trait caused by a single gene with multiple alleles?
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.
What is three or more forms of a gene that code for a single trait are called?
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
Blood types in humans are an example of traits controlled by?
Multiple alleles
When more than two different alleles control a trait?

What is the difference between alleles and multiple alleles?
Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid). A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance. So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles) Yes, or: Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
What three or more forms of a gene that code for a single trait called?
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait.

This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
The three alleles of the single gene that controls blood type are typically referred to as A, B, and O. The A and B alleles are co-dominant to each other, while the O allele is recessive to both A and B.
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What is the multiple allele system?
The multiple allele system refers to a genetic system where a particular gene has more than two alleles present within a population. Each individual carries a maximum of two alleles for a gene, but the population as a whole may have multiple alleles. An example of this is the ABO blood group system in humans.
What is a gene that has 3 or more alleles for a single trait?
